At the research group meeting today, we discussed the recent reports of additional fast radio bursts (FRBs) originating from the mysterious source FRB 121102 by the Breakthrough Listen search for alien communications.
It has been proposed that FRBs are some kind of alien signal. In fact, Lingam & Loeb at Harvard earlier this year suggested FRBs might be beams of light used by aliens to accelerate alien ships into space. Probably not, but a very cool suggestion.
One of the neatest responses to this recent detection was the conversion of the radio signals into audio by redditor u/Arzu1982, which I’ve linked to below. Not sure that the audio provides any insight into the origin of the FRBs, but they are neat to listen to.
